BARCELONA; U.S. Female Shot-Putter Banned After Drug Test

A second United States athlete was disqualified from the 1992 Summer Olympics today, for using the same performance-enhancing substance the first penalized American had.

Bonnie Dasse, a 33-year-old shot-putter who failed to advance to the finals, produced a urine sample showing traces of Clenbuterol, a stimulant that contains muscle-building properties. She became the fourth athlete to be expelled from the Barcelona Games and the sixth to have failed a recent drug test for Clenbuterol.

Earlier in the week, Jud Logan, an American hammer thrower who finished fourth, was disqualified and sent home because of a positive test for Clenbuterol.

And Katrin Krabbe and Grit Breuer, two German sprinters who did not enter these Games, and two British weight lifters who were sent home before their Olympic competitions began also tested positive for Clenbuterol this summer.

Because it is known to have similar effects as anabolic steroids, Clenbuterol, which is used to treat asthma, carries a four-year suspension in track and field, which would effectively end Dasse's career. A two-time Olympian, she has ranked among the top 10 American female shot-putters for nine years.

The other athletes disqualified here after their Olympic competition were Madina Biktagirova, a marathoner from the Unified Team who had taken a stimulant, and Wu Dan, a Chinese volleyball player who had ingested strychnine.

In her appearance before the doping commission of the International Olympic Committee, Dasse admitted she had taken the drug three days before the sample was analyzed on Wednesday.

Prince Alexandre de Merode, the chairman of the commission, told The Associated Press that Dasse said she had been given the substance by a friend.

"She recognized having taken the product," he said. "She didn't try to lie and to give false explanations."

Dasse, who lives in Costa Mesa, Calif., was unavailable for further comment. The United States Olympic Committee said in a statement she had left for the United States this morning on a team plane.

As a stimulant with anabolic qualities, Clenbuterol has had an ambiguous standing with sports authorities. The drug had not been listed by name on the list of substances banned by the International Amateur Athletic Federation, the world body for track and field. It was included implicitly under a general listing for "related" substances that are illegal for use.
